SAFE, SAFE CABINET, AND SIMILAR FIRE-RESISTING STRUCTURE.

Application filed March 5, 1921.

To all whom 1f/may concern.'

Be it known that we, Moens Mosman and CARL BARTELS, both citizens of the United States, residing, respectively, in the city, county, and State of New York, and at Hamilton, in the county of Butler and State of Ohio, have invented certain new and uscful Improvements in Safes, Safe Cabinets, and Similar Fire-Resisting Structures, of which the following is a specification.

Our invention relates to safes, safe-cabinets and similar portable fire-resisting structures, by whatever name designated, and in particular to the wall construction for such structures. We fully recognize the difference lbetween safes and the lighter type of portable lire-resisting structures, sometimes designated as safe-cabinets or cabinet safes, etc., and do not intend, in this description, to confuse the several types of such fire-resisting structures, by whatever name they may be designated. However, in order to avoid constant and needless repetition, we shall refer to all such structures hereafter under the generic name of safes Safes should be highly heat-resistant and strong and at the same time light in weight and inexpensive to manufacture, and one of the objects of our invention is to provide an improved safe having all of these features.

Another object of our invention is to provide in a safe, having an inner wall and an outer wall, an improved filler for the space between said walls.

Other objects will be in part obvious and in part pointed out hereafter.

Referring to the drawings: Fig. 1 is a vertical section of a safe involving our invention; Fig. 2 is a horizontal section on the line 2-2 of Fig. 1; Figs. 3, 4, 5, 6, 7, 8, 9, and 10, are fragmentary views of the safe wall showing modified forms of the filler.

Similar reference characters designate similar parts throughout the several views of the drawings, in which; 1 designates the front of the safe, 2 the back, 3 the top, 4 the bottom, 5 one of the sides, and 6 the opposite side. In the front is door '7 mounted on hinges 8. The construction comprises an outer box and an inner box forming re- Spectively the outer and inner walls of the Serial No. 449,638.

safe and a filler between these walls of such a character that it forms a strong reenforcement for the inner and outer walls and at the saine time provides spaces between the walls 1n which may be inserted light, heatresistant material, such as asbestos fiber. The filler may be made of comparatively inexpensive material, such as cement, reinforced .or not reinforced, and may be formed in sections, so that the complete walls may be constructed quickly and inexpensively.

One possible embodiment of the invention is illustrated in Figs. 1 and 2 of the drawings, and in which the outer box forming the outer walls for the safe may be constructed of plates of sheet steel or other suitable material, and comprises a top wall 9, bottom wall 10, rear wall 11 and side walls 12 and 13. The inner box forming the inner walls of the safe may likewise be constructed of plates of sheet steel or of other suitable material, and comprises top wall 14, bottom wall 15, rear wall 16 and side walls 17 and 18. The top, bottom and sides of the inner box are extended in the form of receding steps 19 to form the jamb for the door, and beyond the stepped portions are angular flanged portions 2O adapted to .be positioned in such proximity to the corresponding walls of the outer box as to permit of their being welded or otherwise firmly fastened to those members, as at 20.

The filler between the outer and inner walls of the safe is shown to comprise a plurality of filler units or beams 21 substantially H-shaped in cross section and extending substantially the entire span of one of the walls. These units abut each other as shown, and each unit abuts both the inner wall and the outer wall so as to form a reenforcing wall for the outer walls and a reenforcing wall for the inner wall, and providing posts or flanges 22 between these reenforcing walls to render the fillers strong and to keep the reenforcing walls in the desired positions, The door 7 of the safe may be formed of outer wall 23 and inner wall 24 conformed to register with the adjacent steps of the jamb formed by the inner box, as shown at 25 and welded or otherwise joined to wall 23, as at 25. Between the walls of the door a similar filler may be provided as between the other walls of the safe, Specially shaped filler units 26 may be provided adjacent the stepped portions of the jamb and the door to suitably conform with the parts against which they abut.

To construct a safe involving this invention, the outer box may irst be formed of' plates of sheet steel or of other suitable material joined in any suitable manner at the corners, as by welding. The top of this box, however, may be temporarily left off. The inner box may then be constructed, and after the filler units have been properly placed on the bottom of the outer box, with light, heatresistant material 27 in the apertures 28 formed by the filler units, if desired, the inner box is slid into the outer box to rest upon these filler units. Then other filler units may be placed in the desired position between the outer and inner side walls and also on top of the top wall of the inner box. The top of the outer box may then be welded or otherwise fastened in place and the ianges 2O of the inner box welded or otherwise firmly fastened to the outer box. The structure is now ready for the mounting of the door thereon.

Thus it is seen that our invention provides a construction which is comparatively simple and inexpensive to manufacture and one which is light in weight, is very strong and durable, and is highly heat-resistant. Our improved wall permits of the use of material which is comparatively cheap and by the provision of apertures between the inner and outer walls of the safe, light, heatresistant material may be used, and the quantity of heavy material reduced to a minimum. The filler units may, obviously, be fashioned in many various shapes and also may be formed of various different materials. Moreover, many different materials may be used to lill the apertures provided by the filler units, or these spaces may be left empty, if desired. Figs. 3, 4, 5, G, 7, 8, 9 and 10 illustrate modified forms of filler units, which have been found to be satisfactory. The filler units need not abut each other, and any suitable means may be employed for holding them in the desired position. Moreover, any desired lling may be used to fill the spaces or apertures between the filler units, or no filling may be used in these spaces. If the rigid units do not abut each other, the filling may be used to maintain the units in proper spaced relation.

Having described our invention, what we claim is 1. In a safe, the combination with an outer wall and an inner wall, of a filler, comprising a plurality of separate, formed, abutting cement sections, between said walls, and providing spaces.

2. In a safe, the combination with an outer wall and an inner wall, of a filler, comprising a plurality of separate, formed,

laissa-4.-

cement sections, between said walls, and providing spaces, and asbestos fibre in said spaces.

3. In a. safe, the combination with an outer wall and an inner Wall, of a filler, oomprising a plurality of separate, formed, cement sections between said walls, each of said sections abut-ting both said inner and outer walls to form a reenforcing medium therefor, and providing spaces therebetween.

a. In a safe, the combination with an outer wall and an inner wall, of a filler, comprising a plurality of separate, formed, cement sections between said walls, each of said sections abutting 'both said inner and outer walls to form a reenforcing medium therefor, and providing spaces therebetween, and light, heat-resistant material in said spaces.

5. In a safe, the combination with an outer wall and an inner wall, of a built-up filler f between said walls, said filler comprising a plurality of separate, formed, abutting cement sections, between said walls, and forming a continuous, heat-resistant, cement, reenforcing wall for said outer wall and having portions abutting said inner wall.

6. In a safe, the combination with an outer wall and an inner wall, of a filler, comprising a plurality of separate, formed abutting, cement sections between said walls, forming a continuous, heat-resistant, cement, reenforcing wall for said outer wall, and a continuous, heat-resistant, cement, reenforcing wall for said inner wall.

7. In a safe, the combination with an outer wall and an inner wall, of a plurality of separate, formed, abutting cement filler units, substantially H-shaped in cross section, and placed end to end between said walls.

8. In a safe, the combination with an outer wall and an inner wall, of a plurality of separate, formed, cement sections, each substantially H-shaped in cross section, between said walls, and each extending substantially the full span of one of said walls, each of said sections abutting adjacent sections and abutting both of said walls,

and forming a cement reenforcing wall for said outer wall substantially co-extensive therewith, and a cement reenforcing wall for said inner wall substantially co-extensive therewith, said units providing spaces between said walls and between adjacent sections, and light, heat-resistant material in said spaces.
